The latest finding comes from nutrition and immunology respected: Vitamin E boosts the immune system in older people. In an eight-month study of 88 seniors, the scientists found that those taking at least 200 international units of Vitamin E daily had stronger immune responses than those taking little or none. Alzheimer's disease. Researchers tracked 341 moderately senile patients. Those who popped 2,000 IU of Vitamin E took seven months longer to reach an advanced stage of the disease.
Rangit Kumar Chandra, a Vitamin E researcher at Memorial University of Newfoundland, Canada, says more studies are needed to learn who can benefit most and at what dose. Vitamin E thins the blood, so high doses can cause bleeding in people who also take blood thinning drags, even aspirin. Individuals with serious conditions should consult their doctors. But most people over 65, Chandra says, can take up to 200 IU with no side effects and great benefits.
What's the main idea of the passage？
A．People will be in perfect health if they take Vitamin E every day.
B．Study showed that people who took Vitamin E regained their Flexibility.
C．Vitamin E may help prevent Alzheimer's.
D．Vitamin E offers a range of advantage if old people take proper dose of Vitamin E every day.
Evolution is mostly to blame. It has designed mankind to cope with deprivation, not plenty. People are perfectly tuned to store energy in good years to see them through lean ones. But when bad times never come, they are stuck with that energy, stored around their expanding bellies.
Thanks to rising agricultural productivity, lean years are rarer all over the globe. Modernday Malthusians, who used to draw graphs proving that the world was shortly going to run out of food, have gone rather quiet lately. According to the UN, the number of people short of food fell from 920m in 1980 to 799m 20 years later, even though the world's population increased by 1.6 billion over the period. This is mostly a cause for celebration. Mankind has won what was, for most of his time on this planet, his biggest battle: to ensure that he and his offspring had enough to eat. But every silver lining has a cloud, and the consequence of prosperity is a new plague that brings with it a
host of interesting policy dilemmas.
As a scourge of the modern world, obesity has an image problem. It is easier to associate with Father Christmas than with the four horses of the apocalypse. But it has a good claim to lumber along beside them, for it is the world's biggest public-health issue today—the main cause of heart disease, which kills more people these days than AIDS, malaria, war; the principal risk factor in diabetes; heavily implicated in cancer and other diseases. Since the World Health Organisation labelled obesity an "epidemic" in 2000, reports on its fearful consequences have come thick and fast.
Will public-health warnings, combined with media pressure, persuade people to get thinner, just as they finally put them off tobacco？ Possibly. In the rich world, sales of healthier foods are booming (see survey) and new figures suggest that over the past year Americans got very slightly thinner for the first time in recorded history. But even if Americans are losing a few ounces, it will be many years before the country solves the health problems caused by half a century's dining to excess. And, everywhere else in the world, people are still piling on the pounds. That's why there is now a consensus among doctors that governments should do something to stop them.

Directions: There are five reading passages in this part. Each passage is followed by four questions. For each question there are four suggested answers marked A, B, C and D. Choose one best answer and blacken the corresponding letter on the Answer Sheet.
Passage One
Wild and farm birds often get a flu virus. Yet they usually are able to carry the virus without getting sick.
In 1997 six people in Hong Kong died of a different kind of bird flu virus. It is called the h-five-n-one virus. The Hong Kong government quickly ordered the killing of all farm birds there. That stopped the spread of h-five-n-one to people in Hong Kong.
Yet the virus bad already spread to other parts of Asia. It was found in 16 countries between 2003 and 2006.
The h-five-n-one virus first appeared in Africa. This raised many concerns about the spread of the disease. Scientists do not know exactly how bird flu came to Africa. At first, they thought wild birds were to blame. Now, officials with the U. N. Food and Agriculture Organization believe the main cause is trade in farm birds.
The bird flu virus is found in the waste and liquids of infected birds. The virus spreads when healthy birds or people touch sick birds or nay infected (被感染了的) part of sick birds. Right now, the virus is not spreading among person to person. But the virus could change and start spreading among people. Health officials believe that it is even more possible now that bird flu has spread in Africa, and that is why international organizations are working so hard to stop its spread.
The best way to stop the spread of bird flu is to kill all the chickens in an area where bird flu has been discovered. More than 145 000 chickens have been killed in Nigeria since bird fin was first found one year ago.

A. wild and farm birds
